Abstract
The excited levels of have been investigated from the decay of with Ge(Li), Si(Li), and standard scintillation counters. rays of the following energies were observed: 166.5, 360, 558, 576, 661, 710, 720, 728, 828, 900, 915, 981, 1082, 1116, 1283, 1450, 1677, 1509, 1644, 1810, 1837, 2004, 2100, 2170, 2210, 2510, 2559, 2726, 2958, 2991, 3065, and 3157 keV. The half-life of was measured to be 19±0.3 min. With the help of coincidence studies, a consistent level scheme of at 166.5, 333, 828, 1082, 1450, 1810, 2170, 2726, 3157, and 3398 keV has been obtained. Three major positron groups with end-point energies of 3.18 MeV (65%), 2.5 MeV (∼25%), and 1.54 MeV (. Each group probably consists of more than one component. The results including spin and parity assignments of some of the excited levels of are discussed. The half-life of the 166-keV level is measured by delayed coincidence to be less than (0.22±0.05) × sec.
